Determine if each of the following statements is true in general. Provide proofs for those that you think are true and counterexamples for those that you think are false. * (a) x[n] {h[n]g[n]} = {x[n] h[n]}g[n] (b) If y(t) = x(t) * h(t), then y(2t) = 2x(2t) * h(2t). === (c) If x(t) and h(t) are odd signals, then y(t) = x(t) * h(t) is an even signal. (d) If y(t) = x(t) h(t), then Ev{y(t)) = x(t) * Ev{h(t)} + Ev{x(t)} * h(t).
